google-flights-mcp

The most feature-rich MCP server for Google Flights. No API key required.

12 tools for searching flights, tracking prices, comparing cabins, analyzing layovers, and more, all powered by real-time Google Flights data.

Works with Claude Desktop, Claude Code, Cursor, and any MCP-compatible client.

Features no other Google Flights MCP has

• Carbon emissions per flight and per leg (CO2 in kg)
• Price context: Google’s own assessment of whether a price is low, typical, or high
• Price tracking: track prices over time with SQLite persistence, detect drops and trends
• Calendar heatmap: 60 days of daily prices in a single API call
• Cabin class comparison: economy vs premium vs business vs first, side by side
• Nearby airport suggestions: find cheaper alternatives (e.g., EWR/LGA near JFK)
• Layover analysis: connection time risk assessment (tight/comfortable/overnight)
• Aircraft & seat details: Boeing 787 vs 777, seat pitch in inches
• Google Flights URLs: direct booking links users can click
